Show search result based on keywords

Elastic Stack Elasticsearch
1

I am using Elasticsearch version 8. When I try to query a combination of two words that are stored in two different attributes, I get the search result but the record match with post_title are not coming first
For example I have two names saved in ES
Document 1: "post_tile" : "virat kohli king of centuries"
"post_subheading" : "virat kohli king of centuries"
"post_content" : "virat kohli king of centuries ....."
Document 1: "post_tile" : "xyz"
"post_subheading" : "xyz"
"post_content" : "xyz.."
If my search word is "Virat kohli", then i want my search result the search word matching with post_title keyword comes first after that post_subheading and after that post_content and order by latest post come first
Can I get assistance on how to resolve the issue?

Hi,

Try should clause of boolean query and set any boost parameter for each term or match query.

'query' => [
'bool' => [
'should' => [
[ 'match_phrase' => [ 'post_title' => ''.$searchtext.'' ] ],
[ 'match_phrase' => [ 'post_excerpt' => ''.$searchtext.'' ] ],
[ 'match_phrase' => [ 'post_content' => ''.$searchtext.'' ] ],
],
'minimum_should_match' => 1,
]
],
i am using this but its not working as expected

Use constant score query to wrap each match_phrase result.

How about this?

{
  "query":{
    "bool": {
      "should":[
        {
          "constant_score":{
            "filter": {
              "match_phrase":{
                "post_title":"searchtext"
              }
            },
            "boost": 3
          }
        },
        {
          "constant_score":{
            "filter": {
              "match_phrase":{
                "post_subheading":"searchtext"
              }
            },
            "boost": 2
          }
        },
        {
          "constant_score":{
            "filter": {
              "match_phrase":{
                "post_content":"searchtext"
              }
            },
            "boost": 1
          }
        }
        ],
        'minimum_should_match' :1
    }
  },
  "sort": [
    "_score",
    {
      "@timestamp": "desc"
    }]
}

$params = [
'index' => 'elasticpostdata',
'body' => [
'from' => $pageLimit,
'size' => $setLimit,
'query' => [
"multi_match" => [
"query" => ''.$searchtext.'',
"fields" => ['post_title^3', 'post_excerpt^2', 'post_content'],
"type" => "phrase",
]
],
'sort' => [
["post_title.keyword" => ["order" => "desc"]],
["post_excerpt.keyword" => ["order" => "desc"]],
["post_content.keyword" => ["order" => "desc"]],
["post_indate" => ["order" => "desc"]],
["_score" => ["order" => "desc"]],
],
'collapse' => [
"field" => "postid"
]
],
];

above query working perfectly but sorting of result not working as expected
i want search text matching with post_title field comes first in desc order with date
and after that search text matching with post_excerpt comes in desc order with date
and in last search text matchinf with post_content comes in desc order with date

query finds result correct but sorting not working as i want.
